GLOBAL Function/Macro Definitions

Known Limitations with Design
In model, ClrDiagcFlgProxyPrev(boolean) is compared with ClrDiagcFlgProxy(uint8 signal) which is logically wrong. So, change the data type of ClrDiagcFlgProxyPrev to uint8. Please refer MM065A Data dictionary for the same.
The range of the input signal Ford_Veh_V_ActlBrk is 0 to 65535. We are (MM077A_FordMsg415BusHiSpd_SIL/FordMsg415BusHiSpd/FordMsg415BusHiSpdPer1/MissMsgPassd/OutpProcg/SigProcg/CalcVehSpdChksBrkModlCnvn) rightshifting the value of the input signal with RISHIFT_CNT_U16 and Masking the value of the input signal with EIGHTBITMASK_CNT_U16. Then we add the ouptuts of the each operation. If the output value of the rightshift operation and bitmasking operation is greater than range of UINT8, then overflow occurs.
